photographers, conventionally composed, sharply focused, with appealing subject matter such as woodland glades and sunlit gardens. The images, taken in arbitrary locations around the world, slowly dissolve one into another and, as is also the case with their slide shows, there is no sound track. The work was shown on late night television in Germany every night for three months. Visible World exists in a number of other formats; as an artists' book and as an installation of fifteen light tables displaying a vast slide archive. A later version of Visible World (2003) is a collection of 3,000 small-format photographs displayed on a specially fabricated 90-foot long light table. The encyclopedic collection of images – of cities, jungles, deserts, airports, stadiums, monuments, mountains, and tropical beaches, from all over the world – is composed of photographs taken by the artists over the course of fifteen years. An Unsettled Work (2000–06), originally titled Freakshow; Monsters, grew out of Visible World and consists of pictures rejected from the prior work. A marked aesthetic departure from their earlier pieces, this slide projection issues forth violent, sumptuous and otherworldly images. A later series is Views of Airports, a slide presentation of 469 photographs the artists took over a period of two decades. His Work Schilf, 2004, is by Museo Cantonale d'Arte of Lugano. Questions Fragenprojektion (Questions, 1981–2003) is a three-part, 15-channel slide installation, consisting of 243 handwritten questions, with three questions projected at a time. Each set of questions slowly dissolves into the next. The questions range from the profound to the trivial. Examples include: "Can I restore my innocence?," "Why does the earth turn around once a day?," "Does a hidden tunnel lead directly to the kitchen?" and "Does a ghost drive my car around at night?" The installation was the culmination of a series of works composed of absurd questions, including a book called Will Happiness Find Me? (2002). In the later Question Pot (Big) (1986), a large container molded from polyurethane, questions were written all over the inside of the pot in spiral formation. Walls, Corners, Tubes In Walls, Corners, Tubes (2012), the artists present a series of objects with geometrical bodies which have the form of walls, corners, and tubes and are made alternately of black rubber and unfired clay placed on high, white pedestals. Both the shapes of the objects and their titles such as Wand aus Ton (Wall
